Application
Oiliant-NM 150°C oil-resistant rubber heat shrink tubing is engineered for the demanding protection of motorsport wire harnesses. Made from irradiation cross-linked, high-performance oil-resistant polymers, it remains flexible and flame-retardant at elevated temperatures.Oiliant-NM excels in shielding cables, harnesses, and connectors from diesel and hydraulic oils, as well as chemical exposure and abrasion. Whether for special vehicles or motorsport wiring, Oiliant-NMensures outstanding durability and reliability, making it the optimal choice for harsh environment cable protection.
Features and Benefits
• Shrink ratio 2:1
• High-performance oil-resistant rubber, remains flexible and flame-retardant at 150°C
• Excellent resistance to aviation, diesel, hydraulic oils, and chemicals
• Superior abrasion resistance, ideal for motorsports harness protection
